yet another ts problem

This looks like a slightly different problem then the other ones:

R : Copyright 1999, The R Development Core Team
Version 0.64.1  (May 8, 1999)
...

z <- ts(matrix(c(1:9,NA), 5, 2), start=c(1991,1))
na <- is.na(z)
z[na]

Error: subscript (10) out of bounds, should be at most 5
